movement for loosening and removing the' chine having a scoop and anendless conveyor-,c means being provided for delivering materialdirectly from the scoop onto the conveyor.

A. third obj ect of the invention is to provide a scoop mounted on aiifth wheel to enable the same to operate on material on either side ofthe path of the carria e Another object of t e invention is to constructa shoveling and loading machine particularly adapted for use in minerooms and tunnels where the ceilings are low and the head roomnecessarily limited. Y

Y With these and many other objects in view, which will more readilybecome 'apparent as thenature of the invention is` better understood,the same consists in the novel construc tion, combination andarrangement of parts to be more fully described, illustrated andclaimed.

In the accompanyin one sheet of drawings, formin part oit isspecification, like characters o reference are emplo ed in all theseparate views to designate li e characters throughout, and; l

Figure 1 is a side view partly in section of 'a machine constructed inaccordance with the invention showing the same in actual use.

Figure-2 is a top plan view of the device showmg the scoop in aplurality of positions.

The device includes in its general organization a carriage or main frame10 supported v on axles 11 carrying anged wheels 12 supported on rails13.

' A fifthwheel 14 is mounted on the forward f end of the frame. Thefifth wheel is in the open at its front to permlt filling of the scoopextending trunnions 15 to which are pivoted a pairof links 16 that'function as booms to sup` port a scoop 17. The scoop 17 has a'pairofwalls 18 and 19 which cooperate to form the heel of the scoop Vand whichin the loading position of the scoop comprise the back and bottomrespectively of the scoop. A pair of side walls 20 complete thestructure of thescoo which `as shown is and is also open at the endopposite the botf tom 19 to ermit discharge of the contents thereof. ,neach side 20, preferably adja cent the back 18 are lateral trunnions 18which are adapted to extend through eye holes in the ends of the links16, and thus serve as bearingsfor the scoop. The bearings-are preferablyspaced from the open end of the scoop at a distance somewhat reater thanvthe length of the links so that t e dis-v charge end of the scoop mayextend a'considerable distance over the forward end of the carriage whenthe scoop is tilted to the requisite angle for dumping. Dipper teeth 19are located at the forward end. of the bottom wall-19 and a stop 20 maybe provided on the fth wheel 14 to limit downward movement of the scoop.

The sides 20 of the scoop are provided along their forward edge at apoint preferably intermediate the ends ofthe scoop with angularprotuberances 21 having aligned apertures formed therein through whichthere extends abar'22 to which a hoisting cable 23 is attached. Thiscable passes over one end l80 of the scoop and a bracket 24'secured tothe under side of the scoop guides the cable and prevents damage to thesame. v

The main frame 10 of the carriage has a pair of standards 25 and asecond pair ofstandards 26 mounted thereon. These standards supportbetween them a cylinder casting 27 in elevatedposition longitudinally ofthe carriage. The castin 27 has a Vcylinder 28 therein, which is closeat one end and a suit I0 c able bushing 29 is mounted in the other endof the cylinder to slidably return a plunger 30 in position. The outerend of the plunger has a yoke 31 thereon and a pulley 32 is suspended inthe yoke for guiding the cable 23. A stationary bracket 34 is mounted onthe cylinder casting 27 and this bracket carries a pulley 35 for guidingthe cable 23. Rollers 50 and 51 are mounted in rfront of the bracket 34for aiding in retaining the cable 23.

A pair of cylinder castings having cylinders 4Ltherein are pivoted at 43to the carriage frame and plungers 44 having pistons 45 thereon areslidable in the cylinder. The outer ends of these plungers are connectedto arms 46 on the fifthpwheel 14, and by means of this combination .ofelements the scoop is caused to deviate from the axis ofcarriage. f

The cylinders 41 each have inlet ports 50 that communicate through airlines 52 and 53 to a valve 54 and this valve has an inlet 55 from themain air line 56.

The cylinder 28 has an inlet port 57 whichl port communicates through anair line 59 to a valve 6l having an inlet 62 from the main air line 56and an'outlet port 63. A bleeder port 60 is formed in the cylindercasting 27.

An endless conveyor 70 is mounted on the carriage in aiframe 71 in themanner shown and this conveyor leads from a point rearwardly of thescoop to an elevated p'oint rearl.wardly of the carriage to enablematerial to be loaded on the mine car 75.

The carriage is driven through a chain and sprocket mechanism 76operatively connected to a motor 77. Similarly the conveyor 70 ,isdriven by a worm and gear mechanism 79 gperated by a motor 8O on theconveyor frame In actual operation the carriage is brought to the footof the excavation and the valve 61 is opened to permit air in thecylinder 28 to escape through the port 63. This opera- A .tion permitsthe plunger 30 to be drawn into the cylinder 28 to lower the scoop toits oper- .ative position. The motor 77 is .then started to advance thecarriage and directional movement of the same serves t0 load the scoop.When the scoop is fully loaded, the valve 6l is afrain operated to admitair to the working'si e of the plunger 30. As the plunger is forcedoutwardly of the cylinder the scoop is tilted and the material thereinis deposited directly on the conveyor and carried to the mine car 75. 1

The invention having been described, it is to be understood that variousmodifications are contemplated without departing from the spirit of theinvention and Without sacrificing any of the advantages. For example,Iconteinplate employing electrical means for operating the deviceinstead of compressed air, if desired. Only in so far as I haveparticularly pointed out my invention in the appended claims do I desireto be limited.

I claim:

1.l In a shoveling and loading machine, the combination of a carriage, afifth wheel mounted on the carriage for oscillation about a verticalaxis, a conveyer, a scoop, a link pivotally connecting the scoop to thefifth wheel and adapted to translate oscillation of the fifth wheel intosidewise movement of the scoop, said scoop being adapted to deliver itscontents onto the conveyer, a cylinder pivotally supported on thecarriage for oscillation about a vertical axis and having a piston andpiston rod, said iston rod being directly connected to the fi th wheelto effect the oscillation thereof.
